Abstract: A compressive tool having two jaw halves that run longitudinally from a rear to a front end and are connected to each other in an articulating manner and that can be moved from an open into a closed position. The jaw halves each have an intake contour at the rear end, and cooperate with a displaceable part of a compressive contour such that the displaceable part of the compressive contour, when being displaced longitudinally toward the front end of the jaw halves, will move along the intake contours and force the latter apart in order to move the jaw halves from the open into the closed position. In order to create a compressive tool of simple design with which also to implement in simple manner compressive connections at large nominal pipe widths, the geometry of the rear ends of the jaw halves is selected such that the two jaw halves are able to overlap in the zone of their rear ends when in the open position in a manner that their angle of aperture shall be independent of the course of the particular intake contour.

Abstract: A hydraulic device having a nut part with a threaded hole which has an internal screw thread with a defined nominal diameter and with a defined, uniform pitch, and having a screw part which has an external screw thread with the same nominal diameter as the threaded hole and with a defined, uniform pitch, which is screwed into the threaded hole. (In hydraulic devices, screw parts, in particular nozzle bodies, are generally adhesively bonded in place, in order to prevent them from becoming detached. Adhesive bonding has certain drawbacks, since the screw threads have to be free of grease, and in the case of nozzles there is a risk of blockages, adhesive can enter the hydraulic circuit and also process reliability is not ensured during application.) There is provided a slight difference between the pitch of the internal screw thread of the nut part and the pitch of the external screw thread of the screw part. This slight difference in pitch while the screw part is being screwed in leads to an elastic deformation of a plurality of thread turns, with the result that the screw part is secured so that it cannot become detached.

Abstract: The invention relates to a compression tool (2) for the permanent connection of workpieces (14, 16, 18, 30, 34) having two pivot elements (4), which each have a compression jaw (10), and having at least one rotational axis (6), on which the pivot elements (4) are hinged, wherein the inner contours of the opposing compression jaws (10) form a receiving area (12). The present invention is based on the technical problem of disclosing an alternative compression tool (2), with which a permanent connection can be provided between workpieces (14, 16, 18, 30, 34) by axial compression. The technical problem is solved in that the inner contours have at least one sliding face (22), which is inclined relative to the receiving area axis (20). A compression tool (2) can thus be provided which, starting from a radial inward movement, performs a compression in the axial direction, nonetheless requires little installation space, and offers weight advantages due to a smaller axial extension, for example. Furthermore, the invention relates to an attachment for a compression tool (2) and to a method for the permanent connection of workpieces using a compression tool.

Abstract: In a method for error correction of packet data, in particular DAB (digital audio broadcasting) data packets, code words being used over multiple data packets, redundancy information for error correction is added while maintaining the original packet data structure, at the cost of a free data field or a useful data field. The cycle of the error protection is selected as a multiple of a minimum size for a packet length.
